PUMP.

SPECIFICATION forming part of Letters Patent No. 540,200, dated May 28, 1895. Application filed February 15, 1894. Serial No. 500,289. (No model.)

To all whom it may concern.-

Be it known that I, JACOB J.'THIESEN, a citizen of the United States, residing at J ansen, in the county of Jefierson and State of Nebraska, have invented a new and useful Pump, of which the following is a specificat-ion.

My invention relates to pumps, of the class adapted to be operated either by hand, windmill, or other power; and it has forits object to provide a simple, efficient and durable hand power; to provide means for attaching and detaching the operating power with facility, and without the manipulation of bolts, screws, or similar devices; to provide simple and adj ustable means for the attachment of the hand-power to a pump-barrel; to provide means for attaining the accurate axial movement of the pump-rod in the pump-barrel, to avoid binding or cramping during operation; and to provide means for preventing the overflow from the pump-barrel, without closing the upper end of the latter, whereby compression of air or liquid in the upper end of the pump-barrel is avoided.

Further objects and advantages of my invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure l is a perspective view of a pump constructed in accordance with my invention. Fig. 2 is a vertical central section of the same. Fig. 3 is a detail view, in perspective, of the hand-lever and attachments, including its swinging support. Fig. 4 is a similar view of the clutch for connecting the power to the pump-rod. Fig. 5 is a similar view of a slightly-modified form of clutch, which is employed especially for connecting a pump-rod to a windmill plunger-rod when the clutch is arranged at a considerable height.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings. y

1 designates the pump-barrel, which is provided at a point near its upper end with an outlet 2 designed to discharge into a trough the upper end of the pump-barrel to provide an over-flow receiver 3, to receive the surplus water which is elevated by the plungenat each stroke, more rapidly than it can be carried off through the outlet. The upper end of this over-flow receiver, which is a part of the pump-barrel, is fitted with a cap 4, se-

cured in place by contiguous threaded surfaces, as shown, and provided with anangnlar opening 5 for the passage of the pump-rod 6. The plunger is not illustrated in the drawings, audit may be of any suitable or preferred construction, and attached in any serviceable manner to the lower end of the pumprod. The pump-barrel is provided, furthermore, with a lower outlet 7, provided with a cock or valve 8, which may be operated by hand; said lower outlet being adapted to be used to supply water in a building at a point below the plane ofthe tank or reservoir, and without first passing therethrough.

A safety device 9, is arranged in the pumpbarrel, to prevent the bursting of the barrel when the contained water becomes frozen, such device consisting of a short tube 10 communicating with the interior of the barrel, a

glass or other frangible partition 11 located.

in the said tube adjacent to the plane of the inner surface of the barrel, and guard-disks 12 of leather orsimilar flexible material arranged upon oppositesides of and in contact with said frangible partition. When the contents of the pump-barrel freeze the expansion acts upon the frangible partition and causes the latter to break, thus relieving the strain and preserving the barrel. The flexible guard-disks between which said partition is interposed protect the latter and. hold it in place under ordinary circumstances of use and operation, but yield readily to the force of expansion when the contents of the barrel freeze.

13 represents a guiding frame or yoke, provided with the aligned sleeves 14: which embrace the pump-barrel and are 7 secured at their desired elevation thereon by means of the set-screws 15. The frame is provided at its upper and lower ends with the registering guide-openings 16 in which is fitted for vertical reciprocation the slide-rod 17, and fulcrumed between the parallel side-bars 18 of the frame or yoke is an operating hand-lever 19 which is connected to the slide-rod. The connection of the hand-lever to the frame is by means of a swinging loop 20, fulcrumed as at 21 to the side bars 18, the said lever being pivoted, as at 22, between the parallel sides of the loop. The connection between the extremity of the hand-lever and the sliderod is detachable and is constructed as follows: The slide-rod carries a pivot-pin 23, which is threaded at its center in a suitable perforation in the rod and is provided with smooth terminals which project beyond the sides of the rod. The end of the lever is provided with a seat 24 to receive the projecting extremities of thepivot-pin, the lever being bifurcated to pass upon opposite sides of the rod. A bifurcated retaining bolt 25 is slidably mounted in a'keeper 26 upon theupper side of the lever and is adapted, when extended, to close the upper sidesof the seats 24 and prevent the displacement of the pivotpin when arranged therein. An actuating spring 27 is coiled upon the shank of said bolt and, bearing at its extremities, respectively, against aneye 28 on the lever and'the shoulder 29 at the inner end of the 'bifu-rcated portion ofthe bolt, holds the same normally in its extended position; and a thumblever 30 is fulcrumed upon the hand-lever and is connected to the end of the bolt, whereby the latter may be withdrawn to discover the seats 24 and release the pivot-pin.

Coupled to the upper end of the slide-rod 17 is a tubular stem 31, which is fitted, removably, at its upper end in -acollar 32 at one end of the casting 33. The casting is pro vided with a vertical opening 34 in which fits the pump-rod above the upper end of the pump-barrel. The pump-rod fits slidably in the opening in the casting 33, whereby when the hand operating mechanism is disconnegated, by means hereinafter described, the

' pump-rod may slide freely thereth rough when operated by any other power.

Fixed to the upper end of the casting 33, and preferably forming a part thereof,'is a socket-piece 35 provided with parallel ears36 between which is pivoted a rocking latch 36 provided at one end with a pin 37 which aligns with a perforation inthe side of the socket-piece and is adapted to engage one of a series of perforations 38 in the pump-rod. The pin 37 is preferably square orrectangularin cross-section and is tapered'toward its free end, and theperfora'tions 38 are similarly tion I provide-a swinging looped arm 40, having its arms pivotedto the ears 41 at'the opposite side of the socket-piece from the above described ears 36, and bearing upon the outer surface of the latch. The latch is provided near its opposite ends with the shouldered notches 42. When the swinging arm is engaged with the lower notch of the rocking latch the pin of the latter is held in engagement with the perforation in the pump-rod against accidental displacement by jarring or otherwise; and when the said arm is engaged with the upper notch-of the rocking latch, the latter is tipped in the opposite direction and its pin is held out of operative relation with the perforations o'fthe pump-rod. For operating the swinging arm4 0 I providean operating-rod 43 whichis slidabl y fitted in the bore of the tubular stem 31, is connected at its upper end to the said arm, and .is provided at its lower end with a'button 44, arranged in a slot 45 in the side of said tubular stem.

It will be understood that'thehand-operating mechanism, as thus 'far described, can be used only when the windmill,or other power operating devices usually attached to pumps of this class, have been disconnected, and as said power operating'devices form nop'art of my invention I have deemed it unnecessary to illustrate the same in the drawings; The socket-piece 35, withitslockin'g attachments, may be'secured to the rod 6, when it is desired to operatethe pump by-means of the handle 19, but when other-power is enrployed,-said locking devices mustbe disconnected by the meansabove described i'n-or'der'th'at the pump rod may slide f reel'y" through the socket piece. It is obvious that any'suitable' form of device for connecting thepump rod to thewindmill or other power may be ernpldyed-wheiiby, when it is desired to use the'hand-operating mechanism, said device maybe disconnected to release the pump rod.

In Fig. 5 I have illustrated a slightly modified form of the clutch ,just described, in which the swinging arm is provided itsouterend with a series of cross-bars46forthe attachment of the upper end of theoperating-rod, and by attaching said rod to different crossbars a'greate'r or less n o'velnentof the rod is necessary to accomplish the desired movementof the arm. This'form of clutch-(which is identical with'that above describedinother respects), is designed 'for'use in connecting the'plunger-rod of a wind-mill, or other motor, to the upper end of the pump-rod; and it will be obvious that when the device is arranged in connection with a motor of this kind it maybe attached thereto or tofthe hand operating mechanism, as above described, according to which is required, by the simple manipulation of the clutches, the operatingrods of which extend to within easy" reach of the operator.

The operation of the mechanism will be readily understood from the above description, and it will be obvious that various changes in the form, proportion, and minor 7 details of construction may be resorted to or flange 47, which bears upon the periphery of a suitable washer 4:8 placed upon the up per end of the pump-barrel and having the guide opening 5 formed therein. This construction is preferable for the reason that the Washer may be replaced at small expense and is more readily removed and applied, and, furthermore, the angular shape of the pumprod does not interfere with the rotation of the cap necessary to properly engage the threads thereof with those upon the pump-barrel.

It will be noted furthermore that the coupling 49 which carries the lower outlet 7 and the safety device 9 is provided with smoothcylindrical extensions 50 which embrace the adjacent portions of the pump-barrel and prevent the vibration occasioned by the operation of the hand-lever from loosening the joints at this point.

A stop 51 is provided to limit the downward movement of the hand-lever, said stop being clearly shown in Fig. 2 of the drawings, and the hand-lever is provided at a suitable point with an enlargement 52 to strike said stop. A brace 53 is indicated in Figs. 1 and 2, and may be employed as an additional means 'for supporting and preventing vibration of the pump-barrel.

It will be understood from the foregoing description that any desired construction of fastening devices may be employed for attaching the pump to a building or to the tower of the wind-mill, but as these parts may be varied without aifecting the operation or functions of the other features of the pump specific illustration and description are unnecessary.

Having thus described my invention, I
